Problem creating nested xml data using XSQLServlet

Question

Hi,
This is sort of a sql question.
I'm trying to create a nexted xml data file.
The data in a rows format can be had using the
following query...
SELECT username, portlet_name, count(instance_name) as
INSTANCE_COUNT
FROM portlet_user_subscriptions
GROUP BY username, portlet_name
to get is back in a hierrachical format, I tried the
following...
SELECT distinct(username) as USERNAME,
CURSOR (
     SELECT portlet_name, count(instance_name) as
NUM_INSTANCES
     FROM portlet_user_subscriptions T2
     WHERE T2.username=USERNAME
     GROUP BY portlet_name ) AS PORTLETS
FROM portlet_user_subscriptions T1
But, that is running the CURSOE for every username in the
other loop when it should be doing it only for distinct
usernames.
What am I doing wrong here...
cheers,
Vijay

How you store the data in the database?
Basically, you can query the database with XSQL(<xsql:query/>)
to get the output in XML. Then you can use XSLT to transform it
to the format you want.
<?xml-stylesheet type="text/xsl" href="doyouxml.xsl" ?>
